报告简介:

In this presentation, the syntheses of colloidal gold nanocrystals and their plasmonic properties and applications would be described. Gold nanospheres, nanorods and nanobipyramids with narrow size distributions were obtained by seed-mediated growth method. In addition, fine size tuning was achieved through mild oxidation and anisotropic overgrowth, which allows for precise control of the plasmon resonance energies, affording attractive plasmonic features, including their tunable plasmon wavelengths over a wide spectral range, extremely large absorption/scattering cross-sections, and large enhancements of local electric fields and densities of photonic states. Finally, plasmonic applications of the as-prepared gold nanocrystals were described. Examples will include active plasmon switching, plasmonic catalysis, plasmonic sensing, time-temperature indicators and local photothermal heating.
